To all whom t may concern:

'Be it known that I, lil/'Inman C. SCHMIDT, a citizen ot the United States, residing at Richmond, in the county ot Henrico and State oi' Virginia, have invented certain new and useful Improvements in Indicating-Bottles; and l do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel teatures hereinafter described, reference being had to the accompanying drawings which show two embodiments oi the invention,l which I have selected for purposes of illustration, and the said invention is fully disclosed in the following description and claims.

Referring to the said drawings,

Figure l is a vertical sectional view of one form of my improved bottle and closure, with the stopper retracted.

Fig. 2 is a similar view of a modification, with the stopper closed.

3 is a top plan view et the neck parn tition disk.

Fig. Llis a top plan View o'l a tubular member which is adapted to be placed in the neck of the bottle.

Fig. 5 is a similar view of a modified term of neck partition disk taken on line m--zc of Fig. Gis a side view of the bottle neck after said bottle has been originally filled and closed.

Fig. 7 is a similar view showing the bottle open and that an attempt has been made to reiill it.

My invention relates to non-relillable bottles and consists in certain novel and useful improvements in the same and is a division ot my application7 Serial No. 479,737 iiled ret. si, 190e.

rlhe object ot my invention is to provide a closure for bottles intended to contain va rious kinds of liquids, so constructed as to permit the contents of a bottle to be freely poured therefrom but which will indicate with certainty any attempt to insert liquid into the bottle after it has once been emptied or partially emptied of its original contents.

To this end I provide my improved bottle with an indicating device having a part which is adapted to be totally or partially Serial No. 167,266.

destroyed, disintegrated or removed by chemical action, which is set up by liquid coming in contact with a part impregnated with chemicals, thereby carrying with it a word or indication or symbol, showing the contents to be original and on dissolution7 displaying a word or other indication showing the bottle to be refilled.

In the embodiment of my invention illustrated in Figs. l, 3 and il, A designates the neck portion oi.l my improved bottle provided with my invention, and having internal screw threads a as shown. B is a tubular member forming part of the closure igor the bottle and is provided near its lower edge and on its periphery with a screw threaded annular portion b adapted to enthe screw threads a in the neck of the bottle.

F is a packing washer oi"I cork or other suitable material seated in a recess in the neck of the bottle below the threads a, against which the lower end et the tubular 'member B is screwed, to prevent the contents of the bottle i'rom passing the threads and entering a recess C located between the tubular member B and the upper end of the neck of the bottle. rit the top of the tubular member B is an annular disk or liange C provided on its periphery with serrations c and connected to said member B by means oi a screw threaded joint H. The periphery of this disk C is the same in circumference as the inner surface of the neck of the bottle, so that it will tit the same snugly and only permit communication between the recess C and the upper endet the bottle through the openings i'ormed by the serrations e.

K is an inner cylinder located within and forming part or' the member B, and being integral with the same through the medium of ribsd, the openings between the ribs forming channels e. rEhe upper end or the cylinder l has a single `screw thread c2 to receive the shank c3 ot the stopper D and the lower end of said cylinder is closed by means ot a stopper 7: to prevent the outflow ing liquid from the bottle entering said cylinder.

The lower portion of the part B is prorided with an annular partition. l of some suitable transparent sul'ystance, such glass, forming two chambers., one tor each of the two ribbons of the indicator G, hereinafter described. This partition I is in eilfect a baffle and extends upwardly in plane with a circular line drawn through the disk C, a slight distance toward the center of the tubular member B from the inner edgesof the serrations c, so that liquid entering the recess C through the openings formed by the serrations will drop first into the chamber formed between the partition I and the inner surface of the neck of the bottle.

The stopper D may be of any desired form, the one shown consisting of a main portion D provided with the before mentioned threaded shank C3. rllhe stopper is provided with cored washers which close the mouth of the bottle and channels c when the stopper shank C3 is screwed into the opening c2. A ring CZ is placed upon the Y lower end of the shank G3 in order to prevent said shank from being withdrawn entirely from the cylinder l.

rEhe indicator G, which is placed in the recess C', consists of a ribbon G or strip of any suitable material, such as paper, fabric, tape, etc., with an indication of fraud thereon, such as the word Refilled coated with a mixture of a non-transparent substance and chemicals, such as Whiting miXed with a non-hygroscopic substance, as a carbonate and preferably bicarbonate of soda, which conceals the fraud indication. On this coating appears by printing, stamping or otherwise, any desired word or words, marks or symbols indicating originality of the contents, such for example as the word Original which indications are visible through the bottle as shown in Fig. 6.V This ribbon is placed in the chamber formed between the partition I and the inner surface of the neck of the bottle and another ribbon G2 is placed in the chamber formed be tween the partition l and the member B.

This second ribon G2 is preferably lormed of absorbent material, which is impregnated with a non-hygroscopic solid acid, such for example as citric acid, which is easily soluble in liquid.

When an attempt is made to refill the bottle, the inflowing liquid will pass through the serrations c and drop into the chamber carrying theribbon G and the partition I will prevent said liquid from entering the chamber' carrying the ribbon G2 until enough liquid is forced into the outer chamber to overflow the partition, when chemical and mechanical action ensues, which destroys the coating on which the indication of originality appears and the said coating is chemically removed carrying with it the indication of originality and displaying the indication of fraud. The removal of the indication of originality and coating is mechanically accelerated by the carbonio acid gas formed by the action of the chemicals used.

lt is obviousthat fraud indications on the ribbon G', such as the word Rei'illed may be printed as heretofore described, and no further indication printed on the coating, the plain coating being the evidence of originality. ln this case the attempt to refill the bottle would destroy the coating as heretofore described, and disclose the fraud indication, or the plain ribbon might be the indication of fraud, coated as described, with the symbol of originality thereon. ln this case, an attempt toy refill the bottle would destroy the coating and the symbol of originality, leaving the plain ribbon to in-l dicate fraud. Many variations of my improved indicating ribbon may occur in the practical application of my invention.

The embodiment of my invention illus trated in Figs. Q and 5, is identical with the structure heretofore described, except that the cylindrical portion l of the member B is omitted, the threads being formed in the radial ribs L of the disk, Fig. 5, to engage the shank c3 of the stopper D. ln this view the indicating device is shown as a single structure of two ribbons placed 'back to back, the outer ribbon bearing the fraud indication and coating of nonhygroscopic substance and the other ribbon being impregnated with acid. ln these views I have also shown a conical valve X which is loosely placed in the narrowed portion of the neck of the bottle, below the member B. This valve when the bottle is inverted will permit the ready outflow of the contents, but will act as an'additional deterrent to refilling the bottle, and in case an attempt is madeto force liquid into the bottle the valve will close the bottle and positively cause the liquid to floodthe recess in which the indicator is located. y p V rlhe entire indicating device or double ribbon, in this instance, is placed -in the inner chamber formed between the partition l and the outer surface of the member B, and it is obvious that the partition will protect the ribbon. from backward drippings, as said drippings would fall into the outer chamber between the partition and the inner surface of the neck of the bottle. lf an attempt is made to refill the bottle, the outer chamber would be quickly filled and overflow the partition l, and the liquid then entering the inner chamber will cause the chemical and mechanical action, heretofore described, to take place and display the indication of renewal.

lt is obvious that other variations may be made in the details of the construction with out departing from the spirit of my invention and l, therefore, do not limit myself to the exact details herein described and shown. y

What I claim and desire to secure by Letters Patent is l. An indicating bottle of the kind described, having a member in the neck of the bottle provided with a recessforming with the neck of the bottle a chamber, an indicating device provided in said chamber and visible from the exterior of the bottle and comprising layers of suitable material, one layer being provided with an indication and the other layer being impregnated with an acid, and a baffle located adjacent to said chemical carrying materials and acting to prevent return drippinns from outflowing liquid from reaching both chemical or materials carryingq the chemicals simultaneously.

An indicating bottle of the kind described, having in the neck thereof, an in.- dictor visible from the exterior of the bottle, the said indicator comprising a substance carrying a non-hygroscopic carbonate, in conjunction with an absorbent material carrying a non-hygroscopic acid, the acid being easily soluble in liquid, the two chemicals causing a chemical action to take place when inflowing liquid comes into contact with them to disclose an indication of fraud.

3. An indicating bottle of the kind described, having in the neck thereof an indicator visible from .the exteriorl of the bottle, the said indicator consisting of a strip or ribbon coated with a mixture of non-transparent substance and a non-hygroscopic carbonate, and another strip of absorbent material carrying a non-hygroscopic solid acid.

4f. An indicating' bottle of the kind described having in the neck thereof a tubular member provided on its exterior with a recess, which forms with the neck of the bottle a chamber, an annular partition provided in said chamber and dividing the lower port-ion thereof into a plurality of recesses, and an indicator provided in said chamber, visible from the exterior of the bottle and so located relative to said partition that one of said recesses would have to be filled and ofertlowcd with liquid before the indicating device would operate, said indicator coinprising at least two chemicals and a fraud indicating character, and said indicating character being invisible when the contents of the bottle is original, one of said chemicals being adapted to react chemically upon another when in solution caused by inflowng liquid, whereby said fraud indicating character is exhibited to the vision.

An indicating bottle of the kind de scribed, havingl in the neck thereof a tubular member provided on its exterior with a recess which forms with the neck of the bottle. a chamber, an annular partition provided in said chamber and dividing the same inte a plurality of annular recesses, and an indicator provided in said chamber and consisting of a plurality of strips, each of which carries a chemical substance, one of said strips being also provided with a character representing a change in the original contents over which an opaque coating is placed, a symbol of originality provided on said coating, said indicator being visible from the exterior of the bottle and being so located relative to said partition that one of said recesses would have to be entirely filled and overflowed with liquid before the chemical of one strip would react upon the chemical of the other strip to cause the destruction of the symbol. of originality and coating and display the symbol of fraud.

6. An indicating bottleV havingl in the neck thereof a tubular member' provided on its exterior with a recess forming with the neck of the bottle a chamber, a flange provided upon the upper end of said tubular member and having on its periphery a series of serrations through which said chamber communicates with the upper end of the bottle neck, an annular partition provided in and dividing the chamber into a plurality of annular recesses, said partition being in effect a. batlie and extending upwardly in a plane with a circular line drawn through the disk C, a slight distance inwardly from the inner edges of said serrations, whereby liquid entering the chamber through the serrations will drop iirst into the chamber formed between the partition and the neck of the bottle, and an indicator provided in said chamber, visible from the exterior of the bottle and so located relative to said partition that the outer recess must be en tirely filled and overflowed with liquid before the indicating device operates.

7. An indicatinf bottle of the kind described, having in the neck thereof a tubular member provided on its exterior with a re* cess, which forms with the neck of the bottle a. chamber, an annular partition provided upon the lower portion of said tubular member and extending vertically in said charnber and dividingl the lower portion of the chamber into a plurality of recesses, and an indicator consistingl of a plurality of strips visible from the exterior of the bottle, one of said strips beingprovided in each of said annular recesses, the strip in one of said reccsses carrying a chemical substance and an indicating character, and the strip in the other of said recesses carrying a different chemical substance, one of the recesses being adapted to be filled and overiiowed with liquid when an attempt is made to refill the bottle, whereby the two strips are brought into communication through the liquid and the identification of fraud exhibited.

In testimony whereof I aiiix my signature.
